When shopping for essential oils, you’ll often see labels like “steam distilled” or “cold pressed.” These terms describe how the oil is extracted—and understanding them can make it much easier to choose the right product. While both methods are widely used, they apply to different types of plants and result in slightly different sensory experiences.
Steam distillation is one of the most common methods for extracting essential oils from herbs, leaves, and flowers. In this process, steam is used to release aromatic compounds, which are then collected and condensed into oil. This method is often associated with oils like rosemary, where the goal is to capture a clean, concentrated herbal profile.
Cold pressing, on the other hand, is typically used for citrus oils like lemon. Instead of using heat or steam, the oil is mechanically pressed from the peel, preserving the bright, fresh aroma associated with citrus fruits. This method tends to produce oils that feel more vibrant and directly connected to the original fruit.
If you’re browsing different options, you’ll often notice that steam distilled oils are more common for herbs, leaves, and flowers, while cold pressed oils are typically used for citrus peels. Each method is chosen based on what works best for the plant itself.
The simplest way to think about it: steam distillation extracts aroma through vapor, while cold pressing extracts it directly through pressure. Knowing this can help you quickly understand what to expect from an oil before you even open the bottle—and choose based on the experience you prefer.
